Got any friends in London? Tell them to visit the Tube this week to find a personalised gift from Emma Watson.

In a post that the Harry Potter star and the United Nations Women Goodwill Ambassador shared on her official Facebook page on Wednesday, she was seen leaving copies of Maya Angelou’s Mom & Me & Mom at an escalator of a London Tube station.

Emma Watson is doing it as part of a collaboration of her feminist book club, Our Shared Shelf, with Book on the Underground, a community project that aims to promote reading.

The book, written in 2013, is the seventh and the final part of Maya Angelou’s autobiography series. Its copies will be hidden in plain sight twice a month across the London Tube for commuters to find. Once the finders are done reading the book, they can hide it again anywhere on the Tube for others to find.

P.S. The books (about a 100 copies) come with a personalised message from Emma.
